Quien's service as a tauntaun handler at Echo Base continued into[3]3 ABY.[2] On one occasion, at the behest of deck officerCommanderTamizander Rey,[5] Quien took the reins of Han Solo's tauntaun to help him dismount the beast after Solo finished a routine patrol of Hoth's exterior plains around the base's outer perimeter with Luke Skywalker, which ended in Skywalker being attacked by one of the planet's native wampa ice creatures.[3][6] Soon thereafter, once Echo Base discovered that Skywalker had gone missing, Quien volunteered to cover Sector 12 as part of LieutenantCal Alder's search party for Skywalker.[1] Quien instructed base control to set their surveillance cameras to alpha screen.[7]

Quien was killed in the Rebels' subsequent evacuation of Echo Base[8] during the Battle of Hoth, one of the Rebellion's worst defeats of the Galactic Civil War, when a startled herd of tauntauns broke free of their restraints and trampled him. Four others were similarly killed.[1] Following his death, Quien became well-known as one of Echo Base's tauntaun handlers.[9]

Corman Quien was typical of scouts posted at Echo Base.[6] He did not believe his love of animals was a skill that could be put to good use with the Rebellion, but Quien's service at Echo Base demonstrated the success the Rebels achieved by way of making use of their surroundings. He helped Echo Base round up Hoth's native tauntauns, effectively creating an alternative mode of transportation to the Rebels' snowspeeders.[1] Quien, a Human, had brownhair and light skin.[3]

Quien is also referenced in the December2003Wizards of the Coastonline article Hoth: Under the Ice, which identifies the character as obtaining a certain level of notability as a tauntaun handler,[9] as well as the February2004 article Who's Who in Echo Base, appearing in Star Wars Insider 74, which establishes Quien's background as an animal enthusiast. The Star Wars Insider article identifies Quien as being the character behind the off-screen voice in The Empire Strikes Back who announces that he will "cover sector twelve" in the search for the missing Luke Skywalker, and it was the first source to confirm Quien's death at the Battle of Hoth.[1]
